Study on Ship Kelvin Wake Detection in Numerically Simulated SAR Images

To improve ship safety and increase concealment, we introduce a nonconvex regularization with Cauchy-based penalty for discussing the influence of parameters speckle noise in numerically simulated SAR images. First, Kelvin wake geometry was modeled based on classic theory wave generation. Second, scattering echo calculated using two-scale method (TSM). Then, range-Doppler algorithm (RDA), data obtained by TSM were processed to obtain Finally, reconstructed Radon domain Cauchy proximal splitting forward–backward algorithm. The simulation results showed that wakes more easily detected HH polarization large pitch angle X-band, which detection images discussed at different wind speeds. research conclusions are value development stealth technology improvement safety.
